Our economy short blocks are just the ticket for that budget build! This economy short block is a direct replacement for 1993-1995 SVT Lightning 351W applications. Our remanufactured short blocks start as good cores that are dissassembled, then placed in state-of-the-art, environmentally safe burners, followed by steel shot blasting to clean. The blocks are magnifluxed, inspected for cracks, bored and precision honed to manufacturer's specifications. They are then fitted with new, .040"-.060" over cast aluminum pistons and cast rings*. 28-oz. cranks are precision ground to recommended specifications, and micro-polished. Short blocks do not include cam or timing chain. Each economy remanufactured shortblock includes a 90-day, 4,000 mile limited warranty**.
The cylinder bores are machined the minimum amount to bring them in to spec, between .040" & .060". All bores will be the same size. If a cylinder cannot be bored back to true, then a sleeve will be installed so that the block can still be serviceable.
* * * NOTE: Must Re-use original threaded oil filter bung.* * *
*Cast aluminum pistons and cast iron rings are recommended for naturally aspirated combinations only. Not recommended for superchargers, turbos, or nitrous. Always check piston-to-valve clearance when installing aftermarket performance heads or cams.
**Some conditions apply. This is a replacement warranty only. Labor and shipping costs not included in warranty. Installing incorrect parts, Overheating, abuse, or lack of regular maintenance may void warranty.
Testimonial: The best company I have ever dealt with
LRS hands down is doing everything right. Every experience I have ever had with them shows just what an amazing company they are. There is a reason I come back time after time, instead of going to those "other" mustang aftermarket websites. Customer service is the name of their game, and they are winning. It does not matter whether you call, email, forum PM, or go to the actual store, they are always incredibly helpful and enthusiastic. (Getting to see the Cobra R in their showroom was awesome). I'm proud to have the LRS windshield banner on my car, because I know they will always have my back.
